In the drawings, 1' A casing provided with s' end and at its opposit hollow cylindrical the bottom w ll 13 1% ofsaid cast l; opening therein open at both ends aim Wall 14 and extending he chamber nearly to the bottom th The cylinder being considerably smallerthan the Chitinimsszw'e is formed around said cylinder 15, said. passage communicating with the inlet-chamber of the casing 10, which forms an air-pa o from the inlet 1-]. to the inlet end of the finder 15. To the underface of the wali it; of the casing 10 is secured a 1-7, pro dried with a partiin "13}61 wall. I :0 in an Jneinber. 15, ending from said drcoarboii contained Within said reservoir 1-9 lowered to an abnornml osition the float 3 will engra e with the en s of said i lever 29 and lift the valve l additional supply of" hydrocarbon to ass from the admission-pipe 22 throughthe inlet 1 23 to the reservoir 19 20. As soon as suffil cient hydrocarbon has passed into said reser j voir to cause the float 31 to again reach its normal position, as shown in the drawings, l the Weight 725' will operate upon. the valve 24 I to cause it to'again close-the inlet-opening 23 prevent further admission ofthydrocan.

i vided which, by means of a spring 33, a i the inletcup-slmped screen 34 is held over opening As the hydrocarbon passes through the im 22 to the inlet 23 it must necessarily pass through. the screen, 34, and most of the impurities in said hydrocarbon will be prevented'thereby from passing into the reservoir 19 20. The bottom of the easing 12 is provided with it boss in axialline therewith, said boss passing through the botktom of the casing 17 and has threaded theren rtment 19 or the hydrocarbon-reservmr1s .24 25 to permit an Fig. 2.

in position, a packing 37 being interposed. oc-

twecn a flange 38 and the inner wall of the bottom of said casing 17. The boss is provid'edwith an axial opening 3?), extending therethrough into the interior of the casing 12 and communicating with the interior of 'a hydrocarbonmo zzle 40, which extends into the lower end of the cylinder or curring-chainber 15. The nozzle 40 is provided with the usual needle-valve 1] opera-ted by a handle 42 or any other ell-known mechanism. The boss 35 is provided with annular chamber 42*, extending around said boss and communicating through a radial opening 43 with the interior passage 39 of said boss. The annular chamber 412* is covered by a screen 44, through which the hydrocarbon must pass from. said reservoir 19 on its way to the hydrocarbon-inlet nozzle 40.

The hydrocarbon is maintained in normal position in said nozzle 40 at a level iniimedi ately below the exit-opening therein. As the air passes rapidly through the chamber or passage 16 through the interior of the chamber formed by the casing 12 into the bottom of the c linder 15 and passes upwardly around t ve nozzle 40 a suction. is created which will cause the hydrocarbon to be drawn from said nozzle in sufiicient quantities to thoroughly mix with the air passing upwardly in said mixing-chamlmr 15, and the mixture thus Formed will pass through lhe outlet 45 to the engine. Above the well 14 of the casing" 10 is pivotally secured at 46 a plate 47, the shape of which i best shown in Nhen said plate is in its normal or open position, the rear wall 48 thereof will coact with the Wall d9 of the casing 50, secured by bolts 5] to the upper wall i i of the 0 said plate 47. The pivot -16 extends upwardly through the casing 50 and has cls niped thereto arm 51* which may be adjusted. about the axis of said 1:. vet and clamped in any desired position by means of an adjusting-bolt 52-.

The arm 51* is provided with an adjustable member 53 and locking-nut 54, which with the inlet-opening; i1 is a cylinder 56,

closed at the lower end by means Ufa cap 57, in which is a em all orifice 58, vthrough which the hydrocarbon in said co apartment 2U communicates with the inter or of said cyl inder. In the interior of said cylinder 56 is a piston 59, provided with a stem 60, hair ing a. bearing in a boss 61 extending upcfiising 10 and limit the outward movement Wardly into the passage 16, saidsteni being provided with a valve 62, normally closing the greater part of the inlet-opening 11..

ing 11 and forms a bearing for the stem 60, the outer end of which is provided with adjusting-nuts 64 65, interposed between which and said spider 63 is a spiral spring 66, by

regulated. in an obvious manner. The upper Wall is provided With a. cylindrical extension 66, to which is nicely fitted. a cylindrical casing 67, from which radiates a bell-shaped mouthpiece 68, the mouth of which is closed by means of a screen 69. The cylindrical member 67 is split and provided with. ears through Whicha clamping-screw 67* passes and may be adjusted in any position radial to the axis of the boss 66 to extend the mouthpiece 68 iii any direction radial thereto that may be desired and clamped in such adjusted position by adjusting said clampingscrew. By this movement about the axis of the inlet-opening ll the amount of air admitted may be nicely regulated: The upper wall ofthe -zising 67 is provided with an opening in axial line with the piston 59 and Valve 62, through i which access may be secured to the nuts 64 sprin 66 when desired This opening closer h a cap 70, nicely iittil'ig said open ing, said cap beingvheld in position by means of a spring 71, pas'singaround the same and secured to the casing 67 by means of a screw or similar member 7- In the operation of the carburetor the nuts 6 are first adjusted to secure the desired tension of the spring 66 to properly operate the valve 62 and keep it norinall in closed position, as indicated in Fig. 1 of the draw ings. The mouthpiece (SS-is then nicely adjusted about the akisof l d'valve to secure the desired admission. of an for the suitable Working f the carbureter.

As Will e seen by reference to the drawi'ngs, the valve62 does not completely close the inlet-opening 11 when said valve is in closed position; but a certain amount of air may always pass through said inlet-opening through the passage 16 and the chamber in between said piston and the inner Wall 0: the cylinder the movement of said piston will be A spider 63 extends across the inletopen-t which the tension upon said piston may he.

When the piston 59 forces the hydrocarbon in the cylinder 56 through the orifice 58 into the compartment 20, the

hydrocarbon in said compartment 'will rise and at the same time pass through the orifice 21 into the compartment 19. As this orifice 21 is smaller than the opening 58 a much slowerpassage of the hydrocarbon through said orifice will result. i

When the air which passes through the inlet 17 enters the air-passage 16, it will pass through the annular passage between the walls of the casings 12 and 15 into the lower end of said mixing-chamber 15 and will pro duce a suction which will cause the hydrocarbon in the nozzle 4L0 to pass from the orifice therein, the amount of such hydrocarbonxemitted from said nozzle being limited by the needle-valve41 in the usual manner. The hydrocarbon in the reservoir 20, surrounding the chamber '12, is intended to rna' iintai'n a level immediately below the ori ficei in the nozzle 40 and this level is intended surfaces. The maintenance ofv the hydrocarbon always at this level will prevent an excessive emission of said hydrocarbon through said nozzle.

When. the float 31 does act upon the pivoted lever 29, it causes a direct lift of the valve 24 against thc weight of the member 25, this member being guided to move in axial line with said valve. As soon as the float 31 has been lifted by the hydrocarbon thus admitted the valve 24 will again move in a direct line to again close the admission. The screen below the hydrocarbon-inlet prevents impuritics from passing into the reservoir, and the screen surrounding the'annular passage 42* removes any impurities which may accidentally have passed into said reservoir, so that the material which passes into the mixingchamber will be comparatively free from such impurities. 7

By means of the pivoted plate 47 the closing. movement of which is regulated by the adjustment of the member 53, the emission of a greater or less quantity of explosive mixture from the mixing-chamber 15 may be regulated. By this construction of a carbureter a very practical device is' ecured, simple in construction and very effective in its operation.
